Recommended Goals for 
Clean Truck Program

Briefing Overview 
Status of Clean Truck Program 
Commission Motion to Accelerate Seaport Clean Air Goals 
Stakeholder Outreach 
Assistance to Truckers 
Alternative Technologies 
Clean Truck Program Phase 2 options

Trucks Implementation Success 
100% of drayage trucks met or exceeded the mandatory
2010 performance measure 
ScRAPS 
280 drayage trucks removed 
Ended January 2011 
Drayage Truck Registry 
Launching RFID

2011 Puget Sound Maritime Air
Emissions Inventory results 
Airshed-wide DPM from trucks calling at Port of
Seattle decreased 53% from 2005 levels. 
Trucks accounted for 7% of Port of Seattle's
2011 airshed emissions of DPM.

Clean Truck Program Milestones 
PHASE 1: MY 1994 or newer engines 
12/31/2010: 100% of trucks must have model year 1994 engines 
PHASE 2: MY 2007 or newer engines (in current NWPCAS) 
12/31/2015: 80% of trucks must have model year 2007 engine 
12/31/2017: 100% of trucks have model year 2007 engine 
Possible PHASE 3 (under discussion): MY 2014 or newer engines
12/31/2022 or later: 100% of trucks have model year 2014 engine

Trucking Industry Concerns 
Lead time to comply 
Cost of trucks 
Supply of trucks/drivers 
Equity in program administration 
Need for financial incentives & other support 
Consistency with Port of Tacoma requirements

Nov. 28th Port Trucker Meeting

Issues Raised at Port Trucker Meeting 
Can't afford to buy newer truck 
Loss of work makes it even more unaffordable 
Port requirement will increase demand/cost of
trucks 
Need financial incentives to help upgrade trucks 
Need longer timespan to utilize existing trucks 
Trucks are only 7% of Port's diesel particulate
matter emissions

Help for Truckers 
Financial incentive such as ScRAPS 
Information and referral 
loans
small business assistance 
individual development accounts 
job retraining & job searching

Technology Options to Meet 2007
Engine Equivalency Requirement 
Type                    Estimated Costs     Comments 

Diesel powered truck MY 2008+    $45,000 - $125,000    Proven technology 
Repower existing truck, replace     $65,000           Proven technology 
with newer diesel engine 
Install DPF retrofit on existing      $25,000 - $30,000 +   Not recommended for trucks with short duty
engine                     $300/cleaning       cycles 
Repower existing diesel truck with   $ 80,000 - $ 95,000    New comparably-sized engine to be available in
CNG engine                             2013; range/fueling limitations; fuel costs about
$1 - $2 less per gallon than diesel 
CNG engined truck 2007 or newer   $100,000 - $180,000   Range/fueling limitations; fuel costs about $1 -
$2 less per gallon than diesel

Emerging Technologies That May
meet Requirements in Future 
Type                    Estimated Costs    Comments 

Engine retrofit with CNG dual fuel   $35,000           Not yet demonstrated to be equivalent to MY
kit                                                        2007 emission standards; increased
maintenance costs to maintain both fuel systems 
Engine conversion to CNG engine   $ 45,000 - $55,000    No certified product for Class 8 engine; not yet
proven to meet MY 2007 emission standards 
Diesel-electric hybrid retrofit or     $30,000  160,000    Unproven in drayage duty cycle; maintenance 
new build                                   needs unknown; not proven to meet MY 2007
emission standards 
Electric                                         Unknown; more testing needed

Implementation Options for Phase 2 
OPTION A: Voluntary soft target at end of 2015 
OPTION B: All trucks meet 2007 emission standards by end of 2015
with exceptions based on financial need (2-year grace period for
demonstrated need, which expected to be older trucks) 
OPTION C: All trucks meet 2007 emission standards by end of 2015
with exceptions based on age of truck (2003 engines + get 2-year
grace period) 
OPTION D: All trucks meet 2007 emission standards by end of 2016 
OPTION E: All trucks meet 2007 emission standards by end of 2015

Context 
From 2018 onward, all options will result in
same dramatic emission reductions from trucks 
From 2015 onward, ECA will reduce ship
emissions by 74%
